MAX BECK, OF NEW YORK, N. Y.

Application led March 9, 1918. Serial No. 221,472.

To all whom t may concern.

Be it known that l, MAX BECK, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Cushion-Tires and Methods ot Making the Same, of which the following is a specification.

This invention relates to cushion tiresV and to a method of producing them, one of its objects being to provide a tire which is reintorced by cords extending radiallyitherein and which serve to prevent the tire from slipping or .skidding, there being additional cords extending transversely of the t'ead and at right angles to the sides of the tire,

the radial and transverse cordsintermeshing.

A further objectmismto provide certain d of building up thev novelsteps in the rnetll tire so that the same is produced cheaply in sections which can be assembled readily.

`With the foregoing and other objects in view which will appear as the description' proceeds, the invention consists oi certain novel detalls of construction and combinations of parts, and of certain novel steps in the method, which will be hereinafter more fully described and pointed out in the claims, it being understood. that various changes may be made in the construction and arrangement of the parts within the scope of the claims without departing from the spirit of the invention.,wv

ln the accompanying vdrawings the preferred form of the invention has been shown.

In said drawings Figure l is a perspective view illustrating the first step in the method of making the tire.

Fig. 2 is a perspective view of the second step. l

Fig. 3 is a similar view illustrating ann other step.

Fig. 4t is a View ofa portion oi a tire embodying the present improvements.

Referring to the figures by characters ot reference, 1 and 2 designate superposed thin strips of unvulcanized rubber and interposed between these strips is al network of waterproofed cords 3 which are preferably about one sixty-fourth of an inch in diurneter and are interwoven to form a coarse fabric, certain of the cords being extended longitudinally of the fabric While the re- Specification of Letters Patent.

maining cords are extended transversely.

The three thicknesses of material are4 then or of any other desired cross sectional contour. This will produce a long body oi2 material. ln lgt such a body has been shownmpartly completed. After the body has been ormed it 'is cut by a band saw or t-lie like into suitable lengths which are then. assembled on end upon a base strip 5 of hard rubber located ontbe wheel rim R, and

as shown in Fi Ll. 'line entire tire is then vulcanized to the rim and is readyfor use, l

all of the sections becoming united into a single body,

lt will be noted that when the tire is thus formed many oi' the cords, as Well as the cores, are `extended perpendicularly or radially to the rim, thus affording an eihcient anti-slipping surface.

1What is claimed is y 1. The combination with a riin having side flanges, of arubber base strip fitte snugly between the flanges and upon the rim, and an annular series of blocks resting at their inner ends on the base strip, each block extending from one flange to the other and including a rubber core extending rae dially from the rim and alternate layers of fabric and rubber extending around the core, the outer edges `of said layers and the outer ends of the cores of the blocks forming the tread surface of the tire.

2. -A,`c11sl1ion tire including a rubber base each core;'the outer edges of the said layers 1 and the outer ends of the cores forming the entire tread surface olf the tire.

3. lhe herein descrlbed method of maln ing a cushion tire which consists in placing waterproofed intcrmeshing cords between thicknesses of unvulcanized rubber, pressing the rubber upon and between the cords to form a single strip of cords and rubber,
